Brewster window use the characteristics of total reflection property of the material. When the incident Angle (called brewster Angle of the material) is specified, the Polarization component of S in the incident light is partially reflected, while the P component is close to the full transmission.Sunday offers a variety of Brewster Windows based on UV-fused quartz for UV applications
The high-precision window is made of BK7 optical glass and UV fused quartz, the fused silica quartz window plate is suitable for high power laser that needs good thermal stability, and the window made of N-BK7 material is cheaper, which is suitable for laser applications that pay more attention to cost.Both fused quartz and N-BK7 laser window plates have precision grades of 1/10 lambda surface flatness and 10-5, 20-10 surface quality to ensure minimal interference to the transmitted beam.Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. we can offer 24 inch zygo flatness reports, full CA 600mm windows.Brewster window use the characteristics of total reflection property of the material. When the incident Angle (called brewster Angle of the material) is specified, the Polarization component of S in the incident light is partially reflected, while the P component is close to the full transmission.Sunday offers a variety of Brewster Windows based on uV-fused quartz for UV applications

Beamsplitter is an optical element that divides a beam of light into two beams according to a certain ratio of reflection and transmission.In the usual laser optical system, lighting optical system, spectrometer optical system, beam splitter is a common optical element degree of transmission and reflection percentage, transmission and reflected light polarization state to carry out segmentation.We can offer the K9 broadband splitter plate elliptical, ultraviolet spectroscopic uv spectral wedge, calcium fluoride (CaF2) broadband infrared spectral wedge, zinc selenide (ZnSe) infrared broadband polarization spectral wedge, standard Cube beam spliiter, PBS, NPBS and other standard splitting optics.The function of depolarization splitting prism is to divide the incident light intensity according to a certain proportion of reflection and transmission, so it is an ideal splitter for controlling the application of laser beam.The function of a polarization spectroscope (PBS) is to divide incident light according to a certain percentage of reflected and transmitted light according to the corresponding polarization state of light.

Conventional Beam splitter cube is consist of two right angle prisms. one of the cant face will be coated metal coating or medium which has good reflective. Other faces will be coated AR coating.

Sunday Optics offer 600mm size window with full CA test by 24 inches Zygo Interferometer
The Standard Window Glass is N-BK7 or Fused Silica, but when manufacture,Fused Silica is more easy to keep its flatness stability. UV Fused Silica is better for UV wavelength, high power laser, the UV tranmission can be 185nm.

BK7 Glass is aways used for visible light and near infrared, it is more economy and used for low laser as a protect window.Sunday Optics advantange is: within 600mm windows, we can offer full CA test reports, 1/10 lambda at 600mm is achieved.

Sapphire has superior optical transmission qualities for ball lens and half ball lens.
Ball lens is used to improve the signal coupling between optical fiber, transmitter and detector, improve the signal quality, and can also be used in endoscopy, bar code scanning, aspherical lens preprocessed materials, sensors, etc. The ball lens has a short focal length, which minimizes the distance needed to travel from the ball lens to the fiber. Ball lens commonly used in the optical fiber coupling, laser collimating device, Optical Measurement System, it has a shorter focal length and the characteristics of small size. Sunday produce ball lens, half ball lens, Super hemisphere ball lens, hollow ball lens.Sunday Optics can manufacture ball lens Minumum diameter 0.3mm.Sapphire has superior optical transmission qualities for ball lens and half ball lens.
